When the rotary drum 800 is used, when asphalt is cut, certain soil is cut at the bottom of the rotary drum 800, the height of an asphalt column is increased to a certain extent, certain influence is brought to the thickness of the measured asphalt, when asphalt is cut by the rotary drum 800 in a secondary description, the rotary drum 800 is normally cut and rotated anticlockwise, after the completion, the rotary drum 800 is brought out through the lifting table 100, meanwhile, the rotary drum 800 can rotate clockwise after coming out, the scraping plate 502 in the inner side of the bottom of the rotary drum 800 rotates clockwise along with the rotating force, one end of the scraping plate 502 rotates in the sliding groove four 501 by using the torsion spring rod 503 as the center, meanwhile, the torsion spring rod 503 also has an auxiliary effect on the rotation of the scraping plate 502, when the rotation of the two scraping plates 502 in the sliding groove four 501 is mutually alternated, the asphalt column at the bottom is pushed downwards by using the pressure spring at the top of the pressing seat 900, the soil hardness is smaller than that of asphalt, the scraping plate 502 is driven by the clockwise rotation of the rotary drum 800, the soil at the bottom of the asphalt column is cleaned, the complete asphalt column is guaranteed, the measuring accuracy is improved, the measured value of the measured asphalt column is completely by using the torsion spring rod 503, and the four scraping plates are simultaneously pressed by the four scraping plates after the four scraping plates are completely pressed by the four scraping plates, and the four scraping plates are simultaneously, and the four-dimensional limitation is achieved, and the four-limitation is achieved by the measuring the rotation of the scraping plate 900.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
